Comment on "Chaotic orbits for spinning particles in Schwarzschild spacetime"

Abstrakt

The astrophysical relevance of chaos for a test particle with spin moving in Schwarzschild spacetime was the objective of C. Verhaaren and E.

W. Hirschmann in [Phys.

Rev. D 81, 124034 (2010)].

Even if the results of the study might appear to be qualitatively in agreement with similar works, the study presented in their work suffers both from theoretical and technical issues. These issues are discussed in this comment.
